Question
I'm trying to install the HENNGE Device Certificate on my device, but I see the following message:
Profile Installation Failed
A connection to the server could not be established.
What should I do?
Answer
The authentication ID (MAC, IMEI, UDID, GUID) listed in the file used for HENNGE Device Certificate registration may be different from the authentication ID of the device attempting to install the HENNGE Device Certificate.
Please check the consistency of the authentication ID and, if there is a discrepancy, could you kindly update the TSV file for HENNGE Device Certificate registration with the correct ID and then re-register the HENNGE Device Certificate?
